“…• One well pattern deployment: The distribution of small well spacing can fully utilize reserves, provide favorable conditions for the positive effect of stress interference to be fully utilized in the original stress field, and the development effect is better than the infill well pattern. • Well spacing-coordinated design: Based on the single-well EUR prediction (Valko, 2009;Clark et al, 2011) and lifecycle economic model (Chitwood et al, 2005), the singlewell control range can be estimated; a reasonable initial well spacing can be set based on lateral length, and fracture length can be determined based on fracturing simulation and reservoir engineering evaluation. • Refine the development layer: The flow units are divided based on geomechanics.…”

Oil prices have fallen dramatically to the average range of USD $30 to $50 per barrel and are expected to stay in this average range through 2017 or beyond. Field development costs for deepwater have fallen but are still a major obstacle to efficient field development and this is not expected to change in the foreseeable future. A failure to adapt to this new economic reality could seriously impact the industry. New strategies and concepts are needed to ensure a sustainable deepwater industry, especially for the more challenging reserves. This presentation will discuss a step change solution to providing a field development concept that will be economic in today's conditions. New strategies and concepts for deepwater field development will be discussed for a cost-challenged environment. Partnering and development strategies will be defined, as these will facilitate subsea development of the most challenged assets and could reduce project cost by up to 30% and to shorten project schedule by 18 months to 2 years. This paper will discuss the following: Development strategies to go forward for a cost-challenged deepwater businessNew development concepts for field development, including processes and equipment beyond Jules Verne conceptNew partnership models to allow for economic provision of resources: utilities, water, etc.Standardization recommendations. Major changes are needed to empower the move to an economic field development concept and these will be discussed with details showing the future of deepwater development.

Surveys from the U.S.G.S, notably, have recently re-assessed the Arctic Circle and its deepest parts. Geology-based probabilistic analyses have found that significant oil and natural gas reserves, about 25% of the world's undiscovered resources, may be held in the deep Arctic Alaska (Bird, 2008; Houseknecht et al, 2010). Such studies are of the utmost interest for developed and emerging countries to help them meeting their growing demand in fossil fuels. As of today, the bulk of investigations, projects and technical papers concerning drilling for arctic oil and natural gas resources, have concerned the onshore hydrocarbon accumulations or the near shore deposits (OTA, 1985; Bercha, 1984; Matskevitch 2006; MMS, 2008). However, when trying to access the arctic deeper waters, only a few structures are available today to drill in these polar environments. Offshore operations in the Arctic Ocean are essentially impacted by extremely cold weather temperatures yielding the presence of sea ice, icebergs, floes and long period of darkness. Nevertheless, deepwater drilling and production in the Arctic Ocean provides an attractive but extremely ambitious challenge for our industry. Because the U.S. Beaufort Sea has an average water depth of 3,240 ft, deepwater drilling provides an interesting and innovative option to develop enormous reserves of oil and natural gas. This paper presents a conceptual study for exploratory and development wells in the harsh deepwater arctic environment of the U.S. Beaufort Sea by using a modified and winterized drill-ship with ice strengthened material or an icebreaker converted into a drilling vessel. In addition, ice management is discussed, considering a fleet of at least two icebreaker vessels to guaranty station keeping in first year sea ice and multi-year sea ice environments in order to conduct year-round operations with the floater. Also, the drilling and production phases will be discussed even in presence of icebergs or large ice floes. Finally, the paper briefly covers environmental regulations and economics. The main goal of this study is to help the oil and gas industry breaking the last barrier in exploration drilling and production by proposing structures and facilities that will enable to operate year-round in both open water and permanently ice-covered waters of the Arctic Circle.
